Application filed January 4, 1917. Serial No. 140,528.

To all whom it may concern;

Be it known that I, Loers MEYER, a citizen of the United States, and a resident of the city of New York, borough of Bronx, in the county of Bronx and State of New York, have invented a new and Improved Printing-Press, of which the following is a full, clear, and exact description.

My invention relates to printing presses particularly adaptable for printing on continuous ribbons or tapes.

An object of the invention is to provide a simple, inexpensiveand efficient printing press whereby sections of ribbon or tape of different lengths can be printed on the press.

Another object of the invention is to provide a press whereby two colors may be printed.

With the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts as herein fully described, illustrated and claimed.

In the accompanying drawings, forming part of the application, similar characters of reference indicate corresponding parts in all the views.

- Figure 1 is a longitudinal section through a press embodying my invention on line 1-1, Fig. 2;

Fig. 2 is a top plan View;

Fig. 3 is a longitudinal section showing diagrammatically the relative position of the various parts during the first operation, that is, during the impression with the first color;

Fig. 4 is a similar view showing the relative positions of the parts when the second color is printed;

Fig. 5 is a similar View showing the position of the parts when the tape is fed through a predetermined length;

Fig. 6 is an enlarged sectional view through the'tension means on the printing roller;

Fig. 7 is a perspective view of the guide carrying the tension device;v

Fig. 8 is a perspective view of the grip control;

Fig. 9 is a perspective view of a corner of the type-carrying plate; and

Fig. 10 is a cross section through the bed and type-carrying plate.

Referring to the drawings, 11 is the press frame in which a supporting drum 12 is mounted to revolve. A bed 13 supported by rollers 14 also bears on the drum 12. .i type-carrying plate 15 is mounted to slide longitudinally on the forward end of the bed 13. The type-carrying plate has suitable means thereon for securing two independent chases 16 suitably spaced from one another. The motion of the plate on the bed is adjustable by means of set screws 17 provided on brackets 18 secured to the bed. The screws are disposed to engage a boss or projection 19 on the bed 13. When the set screws near the forward end of the plate are brought against the bosses 19, the forward chase 16 will be in position to properly print on tapes 20 which are carried by the pressure roll 21 mounted to revolve in the frame 11 above-the bed lVhen the plate 15 is moved rearward, to bring the set screw 17 near the front of the plate in engagement with the boss 19, the front chase will be in-position to properly print on the tapes 20.

The rolls of tape to be printed are carried in a trough or receptacle 22 supported by the frame 11, suitable partitions 23 being provided therein for properly spacing the tape rolls. The pressure roll 21 carries a transverse guide 2% in which tension devices 25 are mounted to slide longitudinally of the guide, to properly engage the tape on the roller. Each tension device comprises a yielding member 26, one end of which is secured to a sliding block 27 engaging the guide 2%, and the other end of which is adapted to bear on the tape passing thereunder and supported by the printing roller.

21 set screw 28 is provided in the guiding block for varying the pressure of the yield ing member upon the tape.

The tape 20,- from the pressure roller, passes over a supporting ba' 29 of the gripping mechanism, which is located on the extension of-the frame in the rear of the press. From the support the tapes pass to rollers 30 which have a frictional engagement with the shaft 31 to which rotary motion is imparted.continuously by some suitable means not shown. The friction between the shaft 31 and the rollers 30 is such that they are only able to take up slack caused in the tape between the printing roller and said rollers 30.

The supporting bar 29 of the gripping mechanism 32 is carried by a frame 33 which is adjustable on the rear extensions of the lltlt] frame 11 through the medium of set screws 34 mounted to engage bosses 35 on the extensions of frame 11. A shaft 36 is rotatably mounted in' the frame of the gripping mechanism 32. A pair of sharp-toothed combs 37 are secured to the shaft 36 so that the sharp teeth of the combs may come into engagement with the bar 29 when the shaft 36 is revolved. The movement of the combs toward the bar is resisted. by springs 38 which tend to maintain the combs away.

from the bar.

An arm 39 is secured to each end of the shaft 36 to revolve therewith. At its free end each arm carries a roller 40 which is to be engaged by a corresponding cam 41 secured to a plate 42 disposed transversely of the bed. Said plate is secured to a flexible sheet 43 the rear edge of which is an chored to the rear edge of the bed The front edge of the sheet 43 is bent upwardly to lie against the biased front edge of the plate 42 and to facilitate the engagement of said edge with Wedgeshaped tongues 44 provided on the re: r edge of the typeca1.'ry ing plate 15. The tape 20 which lies above the plate 42 is protected therefrmn. by a guard 45 extending from the rear edge of the bed 13 over said plate, as best shown in Figs. 1 to 5 inclusive.

Each of the cams 41 has a slot 46 engaged by a screw 47 which anchors the cam to the plate 42. This arrangement permits an adjustment of the cam 41 relative to the roller 40 of the arm 39. The roller 40 has also an adjustment relative to the cam 41 by means of the set screws 34, but this adjustment is very limited. The cam 41 has a rearward extension 48 on which slides a cam portion 49 which is normally maintained against the main body of the cam 41 by a spring 50. The slide 49 of the cam has an arm 51 the length of which may be varied. The free end of each arm of the cams is adapted to be engaged by a corresponding arm 52 mounted to swing on the frame 11 (see Fig. 1). The said arms are. engageable by cams 53 provided on the end walls of the pressure roller 21. The end walls of the roller have arcuated slots 54 wherein the cams are adjustable so as to operate the levers F at predetermined angular displacements of said pressure roller. The pressure roller 21 has a tooth 55 for engaging a projection 56 on the bed to move the bed when the roller is rotated in the direction of the arrow, shown in Fig, 1, against the resistance of a weight 57 secured to the rear end of the bed. The tooth and projection serve for bringing he chases in. proper rcgister with the pressure roller. The weight 57 serves to restore the bed 13 to its initial position when the roller leaves the chases. 7

hen two colors are to be printed on the ribbon, the type-carrying plate 15 is moved inwardly until the front set screws 17 strike the boss 19. This will bring the front chase 16 into position (see Fig. 3). The movement of the bed inwardly will. bring the wedgeshaped tongues 44 f the plate into engagement with the plate 42, raising the same, and in consequence bringing the lowermost points of the cams 41 above the rollers 40 of the arms 39. The pressure roller 21 is then rotated, displacing the bed in the direction indicated by the arrow in Fig. 3. The bed 13 and the plate 15 will therefore move, and the tapes carried by the roller will come into engagement with the rear chase 16.

As the pressure roller is returned the'bed moves therewith, but the rollers 40 will not be engaged by the cams 41; therefore the gripping mechanism will not be operated, and as the printing roller is returned the tape that has been wound on the rollers 30 will unwind therefrom, for the tension device will prevent any slipping of the tape. As the roller leaves the chase the tooth 55 will be in engagement with the projection 56. Under the influence of the weight 57 the bed will be returned to its initial position. As the plate 15 is drawn on the bed to bring the rear set screws 17 against the projections 19, the plate 42 will be released and drop under gravity on to the bed 13, thereby bringing the cams 41 into the path of the rollers 40 when the bed is moved by revolving the pressure roller 21 (see Fig. 4).

In the return movement of the bed the rollers 40 will ride on their corresponding cams 41, bringing the sharp teeth of the combs on to the tapes thereunder. The teeth begin to engage theribbon at the moment when the pressure roller leaves its contact with the chase, that is, on the latter part of the return movement of the pressure roller. In view of the fact that the springs 50 maintain the sliding part 49' of the cam against the main body of the cam, the roller 40 will pass on to the sliding part 49.

To release the teeth of the combs from the tapes the'sl'iding parts 49 of the cam must be moved beyond the roller 40 to permit the same to drop so as to allow the spring to raise the combs from the bar. To this endthe pressure roller must be rotated in the direction shown in Fig.5 until the cams 53 engage the swinging arms 52 and swing the same until the sliding parts 49 are moved to allow the rollers resting thereon to drop, as indicated in Fig. 5. By adjusting the cams 53 the engagement of the same with the swinging arms will take'place sooner or latter. In consequence more or less tape will be pulled from the supply rollers resting in the trough 22. It is self-evident that the greater the angular displacement of the pressure roller after the combs have been made to engage with the tapes, the greater will be the section of tape pulled from the supply rolls.

The adjustment of the cams on the plate 42 allows the proper adjustment between the gripping means at the time the roller leaves the chase.

As soon as the teeth have disengaged the ribbon, the slack that would have been pro duced by the revolving of the printing roller to bring the tooth 55 into engagement With the projection 56 of the bed is taken up by the tape rollers 30.
